Thanks, Robert,
The 'Subject01.ds' was in the search path. The error occurred whether I was
in the same directory as the 'Subject01.ds' or not. When I typed the command
while in the same directory as the 'Subject01.ds', I got this:
CTF_READ_RES4 [v 1.12]
...done ( 0.79 sec)
??? Error using ==> read_fcdc_header
could not read CTF res4 header file
Error in ==> preprocessing at 219
hdr = read_fcdc_header(cfg.headerfile);
Regards,
Hoi Fei

Some parts of the tutorials use CTF specific applications. That is
commercial software only available to CTF MEG users. However, you can
skip those parts of the tutorial. Furthermore, I think that there is
a tutorial that refers to MRIcro, you can get that here: http://

you can copy and paste all matlab instructions from the pdf into the
matlab command line window. I will also make the demo scripts
available for download on the website, but I won't be able to do that
immediately.

Are you at the right location with Matlab? I.e., if you type "pwd",
does that correspond with the directory where Subject01.ds is located?
